[scratches head]
David, I really do not understand your reply. I use both Olympus and Panasonic lenses, mostly on an Olympus E-M5; I have one other Panasonic lens (45–175) which DOES show a Manufacturer Profile, but my 25mm f/1.7 and 12–32 do not. Is this difference/lack down to Phase One, or Panasonic?
And what about Panasonic lenses such as the 15/1.7, 42.5/1.2, 42.5/1.7, and the newly-announced 12/1.4? FWIW, I had a first-version 20mm Lumix, which had and has a C1 preset. It does appear to me that Capture One favours Olympus over Panasonic as far as lenses are concerned.
I am still looking for that brick wall.
